Answers

Answer:

A

Step-by-step explanation:

Find AB using the Law of Sine:

[tex] \frac{AB}{sin(C)} = \frac{AC}{sin(B)} [/tex]

Thus:

[tex] \frac{AB}{sin(40)} = \frac{47}{sin(103)} [/tex]

Multiply both sides by sin(40)

[tex] \frac{AB}{sin(40)}*sin(40) = \frac{47}{sin(103)}*sin(40) [/tex]

[tex] AB = \frac{47*Sin(40)}{sin(103)} [/tex]

AB = 31.0056916 ≈ 31.0 cm (nearest tenth)

The ratio of students to teachers at a school is 19 : 1. At this school, there are 400 people (teachers and students). How many of these 400 people are students? (enter number only, without the unit)

Answers

Answer:

There are 380 students and 20 teachers.

Answer:

380

Step-by-step explanation:

Let 19x =  no. of students

        x =  no. of teachers

Then,  x + 19x = 400

20x = 400

x = 20

19x = 19(20) = 380

your second point will be (2,-5) x=2 y=-5. your first point will be (0,-2) x=0 y=-2.  connect them to make a line.

Step-by-step explanation:

So I’m doing this right now. Basically, you need to create a chart.

x and y. So if x=0, solve for y. You need at least 2 points like this to solve it.

I’ll choose 0.

y=-3/2x-2

y=0-2

y=-2

your first point will be (0,-2) x=0 y=-2.

I’ll choose 2.

y=-3/2x-2

y=-3/2*2-2

y=-3-2

y=-5

your second point will be (2,-5) x=2 y=-5.

in 1990 Jamaica's population of 2,466,000 was expected to grow exponentially by 1.1% each year. what is the range of the exponential function that decribes this growth​

Answers

Answer:

Initial population is 2,466,000 ( p0 )

Growth is 1.1% each year ( r=1.1

p(t)=p0(1+r)t

After 30 years, the population of Jamaica should be 3.42 million by that calculation, but it is only 2.95 million, so apparently that growth rate was a little high, or wasn’t sustained.

Compare the graph of f(x) = 6x and the graph of g(x) = 6x – 12. Then complete the sentence. The graph of g is a _____ translation of the graph of f _____ units _____.

Answers

Answer:

The graph of g(x) is a vertical translation of f(x). Although both have the same x coordinates but different y coordinates.

The graph of g is a vertical translation of the graph of f 12 units downward.

Step-by-step explanation:

The equation y=f(x)+k represents that when k is negative, the graph moves downward.

The  complete the sentence is The graph of g is a vertical translation of the graph of f 12 units downward.

What is Translation?

Translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.

Given:

f(x) = 6x

and, g(x) = 6x – 12.

As, -12 shows the vertical translation of 12 units.

Also, The graph of g(x) is a vertical translation of f(x).

Despite having distinct y coordinates, both objects have the same x coordinates.

So, The graph of g is a vertical translation of the graph of 12 units downward.

A recipe for cookie dough calls for three and two third cups of flour. Jane only ha 1 and three fourth cups of flour. How many more cups of flour does Jane to make the cookie dough?

Answers

Answer: Jane needs 1 11/ 12 cups of flour more to make the cookie dough

Step-by-step explanation:

Recipe for cookie dough= 3 2/3cups of flour

Amount of flour available for Jane = 1 3/4 cups of flour

Amount of flour Jane needs to add to make cookie dough

=3 2/3 - 1 3/4

changing to improper fraction to make it easier to subtract

11/3 -7/4 = (44- 21)/12 = 23/12  =  1  11/12  cups of flour

then,

2x = –2x + 15

or, 4x = 15

or, x = 15/4

or, x = 3.75

Also,

y= 2x

= 2*3.75

Yolanda makes $11.25 per hour at her part-time job. During one week, she worked 12 2/5 hours and also earned some tips. Her final pay for the week was $159.50. How much money did Yolanda earn in tips?

Answers

Answer:

She earned $20 in tips.

Step-by-step explanation:

First, you need to work out how much pay she'd get for 12 hours work:

12 x $11.25 = $135 for 12 hours work

Then, find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:

2/5 of $11.25 = $4.50

Add both these sums together to get her total pay for hours worked:

$135 + $4.50 = $139.50

Subtract that sum from her total pay to find out how much money she earned in tips:

$159.50 - $139.50 = $20

Hey there!

First, we are given:

[tex]\frac{1\frac{1}{4}}{1\frac{3}{8}}[/tex]

To make this easier, I am going to change the fractions in to decimals.

[tex]\frac{1.25}{0.375}[/tex]

To get the unit rate, we can use proportions:

[tex]\frac{1.25}{0.375} = \frac{x}{1}[/tex]

Using cross products, we know that...

[tex]1.25 * 1 = 0.375 * x[/tex]

Now, we solve for [tex]x[/tex]:

[tex]1.25 * 1 = 0.375 * x\\ 1.25 = 0.375x\\ 3 \frac{1}{3} = x[/tex]

Therefore, the unit rate is [tex]\frac{3\frac{1}{3} }{1}[/tex]

Now, do the same with the other problem, and the unit rate is [tex]\frac{1\frac{4}{5} }{1}[/tex]
